Abstract：

A new cutting die structure of round steel bar used in the car was mainly introduced. The structure of an ordinary cutting die was simplified through canceling the upper die components such as upper plate, pressing core, stripper bolt, pressing spring, etc. of an ordinary steel plate die to integrate them in the lower die. By changing the die inserts, variety of round steel bars can be completed in a pair of die so as to achieve the generalization of the cutting die and improve the working efficiency. The outside dimension of the die is 220 mm× 150 mm × 180 mm, and its weigh is only 25.4 kg. By canceling the upper die components such as upper plate, pressing core, stripper bolt, pressing spring, etc. of an ordinary steel plate die to integrate them in the lower die, and variety of round steel bars are cut, which remarkably reduces the development cost. Compared with the ordinary steel plate die, the production efficiency are greatly improved by shortening the stroke with the same working hours.
